ADJUSTABLE CAM-SHAFT THRUST BLOCK.

Application filed July 9,

To all tU/LOIIL it may concern:

Be it known that I, PERRY B. Enwanns,

a citizen of the United States, residing at Athens, in the county ofGreene and State of New York, have invented new and useful Improvementsin Adjustable Cam-Shaft Thrust Blocks, of which the following is aspecification.

The object of my said invention is the 19 provision-of a cam-shaftthrust-block possessed of the capacity of adjustment and thereforeadapted to take up end play and avert knocking of the engine of a wellknown type of automobile.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is a view illustrative of the application of my novel thrust block.

Figure 2 is an elevation of the thrust block per se.

Figure 3 is an elevation of the thrust block taken at right angles toFigure 2.

Figure 1 is a vertical central section of the block taken in the planeindicated by the line H of Figure 2. I

Figure 5 is a cross-section of the block taken in the plane indicated bythe line 5--5 of Figure 3, looking in the direction indicated by arrow.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

My novel thrust block per se is made up of a body 1 of steel or otherappropriate material, a headed and threaded bolt 2 and a nut 3. Thethrust block is shown in Figure 1 connected to a support 13 which may beany appropriate part of an automobile. The body 1 is provided with anend flange 1. and a longitudinal central bore It is also. provided withreduced end extensions 6, separated by a V -shaped space 7, and isfurther provided with shoulders S at the inner end and outer sides ofthe extensions 6, and slots 9 arranged adjacent to but spaced from thesaid shoulders 8. The head 2 of the bolt 2 is tapered in conformity tothe inner sides of the extensions 6, as illustrated.

As clearly shown n F gure 1, my novel 1923. Serial No. 650,559.

thrust block is applied to the middle bearing 10 on the cam-shaft 11 ofthe engine embraced in a well known type of auto- 1 Notwithstanding thepractical advantages ascribed to my novel thrust bar the same is simpleand inexpensive 1n construction and is Well adapted to withstand theusage to which thrust blocks are ordinarily sub-.

jected.

I have entered into a detailed description of the construction andrelative arrangement ofthe parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear and exactunderstanding of the said embodiment. I

do not desire, however, to be understoodas confining myself to thespecific construction and relative arrangement of parts inasmuch as inthe future practice of the invention various changes and modificationsmay be made such as fall within the scope of my inventionas defined inmy appended claims.

Having described my invention, what I claim and desire to secure byLettersPatent, 1s:

1. A thrust block comprising a body having a longitudinal central boreand an end portion and a tapered bifurcation therein and also havingslots adjacent tosaid end portion, in combination with a headed andthreaded bolt, and a nut mounted on said bolt and opposed to one end ofthe body.

2. A thrust block comprising a body having a longitudinal central boreand an end portion and a tapered bifurcation therein and also havingslots adjacent to said end portion, in combination with a headed andthreaded bolt, and a nut mounted on said.

bolt and opposed to one end of the body; the said bifurcation of thebody forming end extensions on the body, and the said end extensionsbeing reduced.

3. A thrust block'coinprising a body lmvthe head of the bolt beingtapered in (FOU- ing a longitudinal central bore and an end formity withthe tapered bifurcation in the portion and a tapered bifurcation thereinbody. 1 and also having slots adjacent-to said end In testimony whereofI afiix my signa- 5 portion, in combination with a headed and ture.

threaded bolt, and a nut mounted on said bolt and opposed to one end ofthe body; PERRY B. EDXVARDS.
